<p>A method for use in a peer to peer remote copy (PPRC) system having primary and secondary storage systems to make data available from established PPRC storage volume pairs includes isolating (88) the secondary storage system to be in a stand alone state such that access from any storage systems and hosts is prevented. It is then determined if each storage volume of the secondary storage system is part of an established PPRC storage volume pair (92). Each established PPRC storage volume pair is then terminated (94) such that the storage volumes of the secondary storage system that are part of the established PPRC storage volume pairs are accessible to hosts. The secondary storage system is then made available to hosts (100) to effect data recovery of the established PPRC storage volumes.</p> |
